Tilted-plated settlement pool

Abstract

A tilted-plate precipitation pool for separating water from sludge is composed of an external cylindrical body, a group of tilted plates, a drive shaft arranged in the center, connected with said tilted plate group and used as water outlet tube, a driver unit and a water gathering unit. The rotating tilted plate group can drive water to form cyclone, so increasing the effect to separate water from sludge.

Description

Technical field: [0001] The invention relates to a settling device in the water treatment industry, in particular to a slant plate settling device which uses water flow to interact with settling tanks to accelerate solid-liquid separation and obtain ultra-high settling efficiency. Background technique: [0002] In the process of water purification, sediment is responsible for removing 80-90% of suspended solids, so its importance is self-evident. [0003] In recent years, the subsequent treatment process of precipitation - filtration, has made great progress in technology. New filter materials, such as microporous filter membranes, plastic fibers, plastic fine-groove discs, and wire mesh, have broken the dominance of quartz sand filter materials, making filter equipment more efficient and miniaturized. However, as the precipitating technology, since the success of inclined tube sedimentation and air flotation slag removal, there has been little progress in the past 20 years...

AI Technical Summary

Problems solved by technology

[0006] 1. The ascending direction of the countercurrent flow is opposite to the descending direction of the sludge, and there will be mud and water top flushing during work, which is a fatal shortcoming that the water production cannot be further improved

[0007] 2. The direction of the same direction flow and sludge slide is consistent, which not only eliminates the top impact on the sludge slide, but also helps to promote the sludge slide, but the collection of clean water is quite troublesome, resulting in a complex structure

At the same time, the distance of the water flow through the sloping plate has been extended to ensure the separation of small sediment flocs and water. However, the water flow will produce a short circuit at the mud collection part, which will affect the water quality of the effluent. It cannot be reduced, which increases the invalid area of ​​the flow section and greatly reduces the separation efficiency. See figure 2
